Title in Portuguese
Métodos de estimação de derivadas via cálculo operacional e aplicações a problemas de controle.
Keywords in Portuguese
Cálculo operacional
Controle (teoria e sistemas de controle)
Sistemas dinâmicos
Sistemas não lineares
Abstract in Portuguese
Este trabalho versa sobre técnicas de estimação de derivadas de forma não assintótica conforme abordagem algébrica de Michel Fliess, e sua aplicação na determinação quase instantânea do estado interno de um sistema dinâmico, cria-se assim estimadores de estado que não se baseiam no observador de Luenberger. Resumo No desenvolvimento do trabalho demonstramos algumas características destes estimadores e apresentamos uma contribuição teórica para viabilizar a implementação destes estimadores em sistemas de controle de tempo real. Posteriormente, um sistema mecânico de dinâmica não linear foi construído e permitiu ensaios em laboratório que atestam, através dos resultados experimentais encontrados, a funcionalidade deste tipo de estimador de estados.

Abstract in English
This work is about derivative estimation technique based on a algebraic and non-asymptotically approach, as devised by Michel Fliess, applied on quasi-instantaneous determination of the internal state of a dynamical system, using state estimators that aren't based on the Luenberger observer. Abstract Over this work we present some particularities of these estimators and a theoretical contribution that will able to implement these algebraic estimators in a real time control system. After that, a non-linear mechanical system was built to verify the functionality of these state estimators.
